Yeah, the GRT website is just being held in place by Gordon's widow as is (my understanding of it). You won't see any of the current development mentioned there. You have to pay attention to the GRT discord. Here is the most recent related directly to the development:
September 19, 2023:
"@here **GRT NextGen Development Status (2023)**
On 19th of January 2022 our beloved friend Gordon died from a viciously escalating condition of leukaemia. He left memories and GRT – the tool we all have embraced in our recreational activities and profession and (as of now) has 65k+ active users around the world.
It took some time to get organized and lay the ground for the continuation of his heritage.
The GRT team is now more than happy to announce, we finally have managed to tackle the challenge to recreate the numeric simulation core and a basic GUI framework to recreate GRT as envisioned by Gordon.
Most of the time went by in the search for the right people with the right skillset and an attitude to dedicate substantial parts of their lifetimes without compensation. We are now in the stage to assemble the major bits & pieces for a very rudimentary reimplementation of what NextGen GRT will eventually become. At the end of next Year (2024) we believe, we can provide the GRT as you know it today based on a totally-from-scratch fresh reimplementation, based on open technology and frameworks.
But there is more to come (beginning of 2025 and onward):
Open and crowd founded GRT pressure measurement devices
Full isotopic simulation core
Alternative GUIs
GRT-Lab for loads and measurements
Native MacOS, Android and iOS support along with Windows and a broader flavour of Linux
Webservice based online version of GRT
Exterior Ballistics calculators
BC calculation wizards
More powder models, bullets and calibres.
DOPE recording integration
Electronic target solutions
Management suite for your weapons and conditions of wear and maintenance
For all of this we need to stay productive on the current level but will also have to invest in expanding the current server infrastructure (Website, GRTGitLab, GRT-Lab, WebserviceGRT…). To achieve this, we will need your support. May it be by sympathy, support for programming or simply with money. We will start our Patreon donation channel, after we have something to deliver. Be prepared for further announcements as things develop.
Here's a first glimpse of GRT NextGen for you

Discord usually has a couple hundred active people... so, that's where you will find out what's going on, not the website.
